Asus PN50 Desktop review
A few weeks ago I bought an ASUS PN50 as a new desktop (to replace an aging Intel Skull Canyon NUC, which was starting to crash once a week – presumably with a hardware fault).

Postfix – qshape

Arduino lights etc.
One day I’ll give up on the illusion that I actually might post something useful here. Thanks to MonkeySailor. over Christmas I did had an Arduino and some lights. But there are loads of tutorials for it (like: http://www.instructables.com/id/Arduino-Controlled-LED-Strip-Holiday-Lighting/ ) , so there’s no point in me trying to document it.
